Used as a precursor in the synthesis of tin-based semiconducting materials, particularly in the fabrication of thin films for optoelectronic devices. Employed in research settings for the development of perovskite solar cells due to its role in forming tin iodide perovskites, which are lead-free alternatives. Acts as a catalyst or reagent in organic transformations, including iodination reactions. Also utilized in the preparation of other tin compounds in laboratory and industrial applications.
